decimal sum = 0; //计算总和
decimal result;
foreach (DataGridViewCell dgc in dataGridView1.SelectedCells)
{
decimal.TryParse(dgc.Value.ToString(),out result);
sum += result;
}
decimal avg = sum / (dataGridView1.SelectedCells.Count);
MessageBox.Show("平均值：" + avg.ToString());
}
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
dataGridView1.Columns[i].SortMode = DataGridViewColumnSortMode.NotSortable;

Answer 2

private Point f1;
private Point f2;
private void textBox1_MouseDown(object sender, MouseEventArgs e)
{
f1 = e.Location;
f2 = this.textBox1.Location;
}

private void textBox1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
this.textBox1.Left = f2.X + e.X - f1.X;
this.textBox1.Top = f2.Y + e.Y - f1.Y;
}
}

试试 可不可以。。。
